Definition
The screaming piha (Lipaugus vociferans) is a species of passerine bird in the family Cotingidae, native to the tropical lowland forests of South America. It is noted for its exceptionally loud, piercing vocalization.
Overview
The screaming piha is a medium‑sized bird, measuring approximately 31 cm (12 in) in length. It inhabits humid evergreen and terra‑fir forest, forest edges, and secondary growth throughout the Amazon Basin and adjacent regions, ranging from sea level to about 1,500 m (4,900 ft) in elevation. The species is widely distributed across northern and central South America, including Colombia, Venezuela, the Guianas, Brazil, Ecuador, Peru, Bolivia, and parts of northern Argentina. The International Union for Conservation of Nature (IUCN) classifies the screaming piha as Least Concern, citing its extensive range and stable population trends.
Etymology/Origin
The generic name Lipaugus derives from the Greek lipaugēs, historically used for certain noisy birds, though the precise original meaning is uncertain. The specific epithet vociferans is Latin for “shouting” or “calling loudly,” directly referencing the bird’s characteristic call. The common name “piha” is applied in Portuguese and Spanish to several members of the genus Lipaugus and related cotingas; the qualifier “screaming” distinguishes this species by the nature of its vocalization.
Characteristics
- Appearance: The plumage is predominantly dark brown with a slightly glossy sheen on the upperparts and a paler, often slightly rufous, underside. Both sexes appear similar, lacking pronounced sexual dichromatism. The bill is short and robust, and the legs are dark.
- Vocalization: The hallmark of the species is a far‑reaching, high‑volume scream that can be heard over several hundred metres. The call is described as a prolonged, strained “eeee‑oooo” or “ee‑eee‑ooo” sound and is most often emitted from prominent perches in the canopy.
- Behavior: Typically solitary or found in small loose groups, the screaming piha forages mainly in the upper canopy, sallying out to catch insects in brief aerial pursuits and gleaning fruits from foliage.
- Diet: Its diet consists principally of fruits—especially those of the Myrtaceae and Moraceae families—and a variable proportion of arthropods captured on the wing.
- Reproduction: Breeding season varies geographically but generally coincides with the onset of the rainy period. Nests are shallow cups constructed of twigs and leaves, positioned on horizontal branches or forks of trees. Clutch size commonly comprises two to three creamy‑white eggs, with an incubation period of roughly 18 days. Both parents participate in feeding the nestlings.
- Conservation: While deforestation and habitat fragmentation pose localized threats, the species’ adaptability to secondary growth and its extensive distribution mitigate immediate conservation concerns.
